Contrast the national median income for a family of four -- $55,775 -- against the average bureaucrat or congressional or presidential staffer, who earns twice what the average American family does (members of Congress earn 3.2 times their average constituent), and the picture becomes clear.
They can't possibly understand the daily life of the average American.
In this context, the GOP proposal to "repeal and replace Obamacare" makes perfect sense. From their cushy perch -- $16000 a year for health insurance is not such a big number.
